ATTACHMENT FOR CARBURETERS.

Specification of Letters Patent.

Patented June 11, 1918.

Application filed March 27, 1917. Serial No. 157,783.

To all whom z't may concern:

Be it known that I, JOHN F. ABEL, of Burlington, in the county of Des Moines and State of Iowa, have invented certain new and useful Improvements in Attachments for Carbureters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to carbureters for internal combustion engines, and the object of the invention is to provide an improved, simple and eflicient attachment for introducing kerosene, air and water into the carbureted fuel within the carbureter whereby greater power will be produced with a sav-- ing of fuel and a minimum formation of carbon in the cylinders.

In the accompanying drawing, Figure l is an elevation partly in section showing my improved attachment secured in place on a carbureter. Fig. 2 is a sectional view of the carbureter.

Referring to the drawings, l ydesignates a carbureter of any preferred form having an inlet 2 through which liquid fuel is supplied; an outlet 3 connecting with the intakek of the engine; and an air induct 4:. The usual throttle valve 5 controls the passage of the gasolene or other liquid fuel to the engine manifold and a needle valve 6 regulates the opening from the reservoir 8 to the upper portion of the carbureter. At a point in the carbureter casing above the reservoir 8 thereof and between the needle valve 6 and the throttle valve 5 I secure one end of a coupling 9, one branch 10 thereof communicating with pipe 12 leading to a receptacle 13 for kerosene, which receptacle is located at any convenient point. The other branch 14: of tlie coupling communicates with a pipe 15 leading to the radiator and is designed to supply water therefrom. Heated air may be entrained into the water pipe 15 through a pipe 16 connected with the exhaust 16 and joining the pipe 15 intermediate the intake and discharge into the branch 14. The casing of the exhaust has a number of perforations 25 through which fresh air is drawn by the suction created by the iow of water through the pipe 15. The point of supply of the kerosene to the coupling is further removed from the carbureter than that of the air and water so as to avoid premature ignition. A check valve 17 may be provided at any convenient point in the pipe 15 to prevent water running into the carbureter when the engine is at a standstill, and I also provide a valve 18 60 abled to introduce into the carbureted fuel sufficient air and water to effect a complete moistening of the mixture supplied to the engine, the commingling of the air and water from the radiator at a point between the needle valve and the throttle valve insuring a mixture which bureted at the time it passes to the engine intake. The kerosene supplied to the fuel along with the air and water produces a superior gaseous product with power and with the further advantage that carbonization is rendered negligible.

I claim as my invention:

In combination with an internal combusis thoroughly car# tion engine and a carbureter therefor, the

latter having a fuel inlet and a valve controlling such inlet, an outlet, and a valve therefor, an oil receptacle, means for supplying moistened oil ladened air to said carbureter comprising a coupling secured at one end to the carbureter casing intermediate 'said fuel inlet and said outlet, said coupling having a branched connection with the radiator of a motor vehicle to receive,

water therefrom, a pipe for supplying air heated by the engine exhaust to said branched connection, and a second branched connection from said coupling to said oil reservoir.

In testimony specification.

JOHN F. ABEL.
